Catalytic Sound was founded in 2011, according to their Facebook page. That’s probably referring to the group’s web site, which appears to be a vehicle for selling CDs. In fact, much of what’s on the Bandcamp site is available in physical form only — CD or vinyl.

Bandcamp, though, makes it easy for the artists to sell music digitally — which means Catalytic Sound dips deep into into the artists’ back catalogues. That’s the part I’m really excited about. Vandermark, in particular, has stacks of out-of-print 1990s CDs represented — such as Drink Don’t Drown, a live recording from the famed Empty Bottle jazz series in Chicago.

One oldie worth checking out is Caffeine, an obscure trio with Jim Baker on piano and Steve Hunt on drums. It’s one of so many “lost” CDs I remember sampling in the KZSU-FM library.

Combined with the Destination: Out store, which is re-releasing the old FMP catalogue of European improv classics, Catalytic Sound is turning Bandcamp into a dangerous vacuum for discretionary dollars. Not that I’m complaining.
